This study examined relationships among personality traits, causal attributions, and global life satisfaction in a sample of 212 high school students. A chief aim of this research was to explore whether causal attributions mediate the relationship between personality characteristics and global life satisfaction as hypothesized by DeNeve and Cooper (1998). Specifically, a mediational model was proposed whereby extraversion and emotional stability relate to causal attributions, which in turn relate to life satisfaction. The results of this research revealed that the personality characteristic of emotional stability, but not extraversion, was related significantly to adolescent life satisfaction. Moreover, this study indicated that adolescents' causal attributions for good events mediated the relationship between life satisfaction and emotional stability. These findings should enhance understanding of potential pathways to the development of increased life satisfaction in adolescents as well as inform adolescent health promotion efforts.Psychology research has focused heavily on the study of psychopathology since World War II. This pursuit has advanced so that understanding of the nature and development of psychopathology far exceeds understanding of adaptive functioning. Seligman and Csikszentmihalyi (2000) recently called for greater attention to the study of positive emotions, cognitions, and behavior. This study examines one such positive psychology construct: life satisfaction (LS). Specifically, this study explores assumed determinants of adolescents' LS, including personality characteristics (i.e., extraversion and emotional stability) and cognitive processes (i.e., attribution styles).LS is the cognitive component of one's sense of subjective well-being. Diener (1994) defined LS as "a global judgment that people make when they consider their life as a whole" (p. 107). LS is associated with a number of positive outcomes for individuals. High LS individuals are more altruistic, tolerant, creative, and mentally and physically healthy than low LS individuals (Veenhoven, 1988). Among adolescents in particular, LS has been shown to moderate the relationship between stressful life events and subsequent externalizing behavior problems . When confronted with stressful life events, adolescents who are high in LS are less likely to demonstrate increased externalizing behaviors than adolescents low in LS. Thus, LS is more than a by-product of life experiences; it plays a critical role in the development of important behavioral outcomes.Researchers have investigated a variety of correlates of LS, including personality, environmental, demographic, and cognitive variables. Broad-band personality variables, such as the Big Five factors (McCrae & Costa, 1990), have demonstrated stronger correlations with adult LS than environmental variables (e.g., life events) or demographic variables (e.g., gender). Specifically, DeNeve and Cooper's (1998) meta-analysis revealed that emotional stability (ES) was the strongest personality c...
